For centuries, a fabled Incan fortress called Ancocogua existed only in legend. Now, researchers think they’ve finally found the long-rumored lost citadel—and new clues about the empire’s last days. In the cover story of our June issue, out now, we venture high into the Peruvian Andes to show how the discovery of a trove of gold and silver sequins—found in what had been an alpaca corral—could help resolve this ancient Incan mystery. Read the article by Alejandro Muñoz at the 🔗 in bio, featuring photographs by Arturo Rodríguez. Also in this issue, we explore inside the epic construction of the world’s tallest church, Barcelona’s Sagrada Familia basilica—an architectural marvel 144 years in the making. We head deep into the Alaskan backcountry with a renegade geologist attempting to predict catastrophic landslides. And we come face-to-face with India’s last lions, now pushing the boundaries of their habitat.
